Summary: "The heroic great hunter Torka, his woman Lonit, and his adopted son Karana emerge from a land forbidden to all men, a land where mountains walk and spirits speak. Across the fierce glacial tundra Torka leads his people -- survivors of a horrifying natural disaster -- to a winter camp where many bands gather to hunt the great mammoth. There he and his followers encounter an evil more dangerous than the wild lands -- the magic man called Navahk who vows cruel destruction of the bold hunter Torka. To survive they must draw upon the courage of one brave boy who will grow to manhood and see with his mind's eye where the sun's light has led them -- to the dawn of man on the American continent."--Cover.
